Ted Reader, one of the most famous celebrity chefs in the world, has prepared a giant hamburger, in an attempt to put his name in the Guinness Book of Records.

The cooking process of the world’s biggest hamburger began at 4 am, on Thursday, when a giant beef patty was placed on a custom barbecue, to slow cook. The burger was unveiled at noon, and it caught the eye of dozens of Toronto passers-by. It was topped off with all the fixings you’d find in an average burger, including lettuce, tomatoes, pickles and barbecue sauce.

The 590 lbs-heavy burger was made with 300 pounds of meat, which makes it three times as heavy as the current record holder. Guinness is yet to acknowledge Ted Reader’s record, but it’s only a matter of time.

The making of the world’s biggest hamburger is part of a marketing tour to promote Ted Reader’s latest cook book, Napoleon’s Everyday Gourmet Burgers. It contains 110 different burger recipes.
